This is a very nice way to work with things that are not textbooks. "OER Recommender links you to open education resources related to web pages you are browsing." Outstanding! I'd like to see a (paper-based) textbook do that! The only real problem I see with it is that it requires the Greasemonkey Foirefox extension, and then another Firefox extension (these also work in Flock). It's not that I don't like the extensions, it's just that I would prefer the feature to be browser-neutral. Much more web-based than browser-based. But this is a very minor criticism of something I think is absolutely pointing in the right direction. Via David Wiley. Related: post on the OER Commons from EDUCAUSE.
